Gem 1: Do normal sound stuff Gem 2: Do normal river stuff Gem 3+4: For all boards+partner boards you can LOSE THE BOARDS, you just need to play all 4 boards. Gem 5: Make sure you do challenge island last because if u do the other 4 gems ull probably have unlocked all minigames and can then continue.
